Introduction
The MBUS is a service-independent maintenance and test bus. No service traffic
goes through the MBUS. The shutdown and reset of the MBUS does not affect the
services on the switch, and faults that have occurred on modules do not affect the
MBUS.
Through the MBUS, the system instructs the MBUS modules on individual cards to
power on/off the cards one by one in turn, thus prevent power surging. The MBUS
module software must support online upgrade.
16
CHAPTER 1: PRODUCT OVERVIEW
Role and function
The MBUS system is powered by 5 V from the MBUS on the fabric. The 5 V power
on the two fabrics are redundant to each other.
Each MBUS module is attached to the MBUS, which contains two control lines:
MBUS0 and MBUS1.
Each card has an independent MBUS module, those on the fabrics are primary
MBUS modules, and those on application modules are secondary MBUS modules.
When the fabrics operate in redundancy mode, the MBUS module on the active
fabric is the active module, and the one on the standby fabric is the standby
module.
The MBUS uses a controller area network (CAN) bus as its control bus, that uses
the 1:1 hot backup and transfers control information at 1 Mbps.
Fan Tray
■
The Switch 8807 uses one 25 W fan tray, which contains four 120 x 120 x 25.4
mm (4.7 x 4.7 x 1.0 in.) axial fan units. The fans can be governed in two
modes: fabric-controlled or temperature-controlled. They operate at -48 VDC
supplied from the backplane.
■
The Switch 8810 uses one 35 W fan tray, which contains six 120 x 120 x 25.4
mm (4.7 x 4.7 x 1.0 in.) axial fan units. The fans can be governed in two
modes: fabric-controlled or temperature-controlled. They operate at -48 VDC
supplied from the backplane.
■
The Switch 8814 uses two 25 W fan trays, each of which contains four 120 x
120 x 25.4 mm (4.7 x 4.7 x 1.0 in.) axial fan units (and totally eight for the two
fan trays). The fans can be governed in two modes: fabric-controlled or
temperature-controlled. They operate at -48 VDC supplied from the backplane.

Family
c
■
The Switch 8800 Family use redundant PSUs. Turn off all PSUs and remove all
the power cords before opening the chassis.
■
Keep the chassis clean and dust-free.
■
Keep the chassis and installation tools away from walk areas.
■
Look carefully for possible hazards in your work area, such as ungrounded
power extension cables, missing safety grounds, and moist floors.
■
Locate the emergency power-off switch in the room before installation. Shut
the power off at once in case accident occurs.
■
Unplug all the power cords and external cables before moving the chassis.
■
Do not maintain the equipment alone when it has been powered.
■
Never assume but check each time that power has been disconnected from a
circuit.
■
Do not place the switch on a moist area and avoid liquid flowing into the
switch.
The Switch 8800 Family are rather big and heavy, so follow the recommendations
below when moving it.
■
Remove all the external cables (including power cords) before moving the
chassis.
■
Do not move the switch alone. Work with another person.
■
Move the switch slowly and stably. Never move suddenly or twist your body.
■
Move the switch at stable and consistent paces with your peer. Keep balance of
your body.
CAUTION: You can only hold the handles at both sides of the chassis when
moving the switch, but not the plastic panel of the chassis, the handle of the fan
frame, the handle of the PSUs or the air vents of chassis.
As these parts are not designed for bearing the weight of the entire chassis, any
attempt trying to carry the switch with these parts may impair the switch and even
injure yourself.
50
CHAPTER 3: INSTALLATION PREPARATION
Wearing an
ESD-Preventive Wrist
Strap
To prevent the electronic components from being damaged by the electrostatic
discharge (ESD), take ESD measures for the area where the switch is located and
note the issues below:
■
Always wear an ESD-preventive wrist strap when installing the parts, especially
the electric printed circuit boards.
■
Hold the circuit board by the edge. Do not touch the components or the
electric printed circuit.
Take the following steps to use the ESD-preventive wrist strap.
Step 1: Wear the wrist strap on your wrist.
Step 2: Lock the wrist strap tight around your wrist to keep good contact with the
skin.
Step 3: Insert it into the hole peculiar to ESD-preventive wrist strap in the chassis
or attach it to the grounding screw of the chassis the alligator clips.
Step 4: Make sure that the ESD-preventive wrist strap is well grounded.
c
CAUTION: For the sake of safety, check the resistance of the ESD-preventive wrist
strap. The resistance reading should be in the range of 1 to 10 Mohm between
human body and the ground.
Safety
Recommendations
against Laser
Some I/O modules of the Switch 8800 Family have optical interfaces. In operating
status, it is dangerous to stare into the open optical interface because the laser
being transmitted through the optical fiber produces a small beam of light which
has very high power density and is invisible to human eyes; when a beam of light
enters the eye, retina may be burned.
c
CAUTION: The laser inside the optical fiber may hurt your eyes.
Examining Installation
Site
The Switch 8800 Family can only be used indoors. To ensure that the switch works
normally and to prolong its service lifetime, the following requirements should be
met in terms of installation environment.
Temperature/Humidity
Requirements
To ensure the normal operation and service lifetime of a switch, proper
temperature and humidity should be maintained in the equipment room.
Long-lasting high humidity in the equipment room is prone to poor insulation or
even leakage of the insulating material. Sometimes, the mechanical performance
deterioration, the rustiness and corrosion of some metal parts are also more likely
to occur. If the relative humidity is too low, the captive screws may become loose
due to the insulation washer contraction. Meanwhile, the electrostatic is likely to
be produced in the dry environment, which will jeopardize the CMOS circuit of the
switch. The higher the temperature, the greater the damage it will do to the
switch. Long-lasting high temperature will speed up the aging process of the
insulating materials, greatly lower the reliability of the switch, and therefore affect
its service life seriously.
Examining Installation Site
Cleanness Requirements
51
Dust is a hazard to the operating safety of the switch. The indoor dust
accumulated on the chassis can cause electrostatic absorption, which may result in
the poor contact of the connector or metal contact point. This happens more
frequently when indoor relative humidity is low, which will not only shorten the
service life of the switch, but also cause communication failure.
The required specifications on dust content and particle diameter in an equipment
room are shown in the following table.
Table 68 Limitation on dust content in equipment room
Mechanical active material
Unit
Content
Dust particle
particles/m3
‚≤3 x 104
(No visible dust on desk in three days)
Note: Dust particle diameter ‚≥ 5µm
Besides the dust specifications, the equipment room of the switch should also
meet the rigorous requirements for the content of salt, acid and sulfide in the air.
These harmful gases could accelerate the metal erosion and the aging process of
some parts. Incursion of harmful gases, such as SO2, H2S, NO2, NH3, and Cl2,
should be prevented. The specific limitation values of these harmful gases are
given in the following table.

Any possible interference sources, no matter outside or inside the system, affect
the switch in use in a way of capacitive coupling, inductive coupling,
electromagnetic radiation, common impedance (including the grounding system)
coupling or conducting line (power line, signaling line and transmission line etc.).
To prevent the interference, you should:
■
Take effective measures against electrical net interference for power supply
system.
■
Separate the working ground of the switch from the grounding device of the
power supply equipment or lightning-protection grounding device as far as
possible.
■
Keep the switch far away from the radio launcher, radar launcher, and
high-frequency devices working in the high current.
■
Adopt electromagnetic shielding if necessary.
A good grounding system is not only the basis essential to the stable and reliable
switch operation, but also an important guarantee of lightning protection,
anti-interference and ESD-prevention. The user must provide good grounding
system for the switch.

recommended to keep one meter of clearance between the rear/front of the
switch cabinet and the wall surface or other devices. If the optional cabinet is
desired, the clear height of the equipment room must be more than 3 meters
inclusive.
Before cabinet-mounting the switch, make sure that the cabinet meets the
following requirements:
■
Better mount the switch in an open cabinet. However, if you want to mount it
in a closed cabinet, make sure of the availability of a good ventilation system.
■
Make sure that the cabinet stands steadily enough to support the weight of the
switch and the accessories.
■
Make sure that the switch fits the cabinet size. Leave some clearance beside
the left and right panels of the switch for chassis ventilation.

CAUTION: For the safety of operators and equipment, the switch must be well
grounded. The resistance reading between switch chassis and the ground must be
less than 1 ohm.
Common grounding environment
Step 1: Remove the screw from the grounding hole in the switch chassis.
Step 2: Wear the connector of the PGND wire accompanied with the switch on
the grounding screw.
Step 3: Insert the grounding screw into the grounding hole and screw it down.
Step 4: Connect the other end of the ground wire to the ground bar of the switch.
n
Generally, the cabinets installed in equipment rooms are equipped with ground
bar. In this case, you can connect the PGND wire of the switch to the ground bar
for it.
Other grounding environment
Following are some methods for grounding the switch in different grounding
environments that you are likely to encounter when installing the switch at
different places.
n
Rather than specifying the switch model or showing the actual location of the
switch power input or grounding screw, the following figures are primarily
intended for illustrating the switch grounding, either via grounding screw or
power input, in specific grounding environments.
■
If a ground bar is available, attach one end of the yellow-green PGND wire of
the switch to a grounding bolt of the ground bar and fasten the captive nuts.
Note that the fire main and lightning rod of a building are not suitable for
grounding the switch. The PGND wire of the switch should be connected to
the grounding device in the equipment room. (For the Switch 8800 Family, the
grounding screw is on the rear panel. Connect it as illustrated in Figure 38).

If there is no ground bar but earth nearby and the grounding body is allowed
to be buried, you can simply hammer an angle iron or steel pipe no shorter
than 0.5 m into the earth. In this case, the yellow-green PGND wire should be
welded with the angle iron (steel pipe) and the joint should be processed
against eroding. (For the Switch 8800 Family, the grounding screw is on the
rear panel. Connect it as illustrated in Figure 38).

You need an AUX cable when configuring the Switch 8800 Family with the remote
modem dial-up approach.
Introduction
AUX cable is an 8-core shielded cable. At one end of the cable is an
RS-232-compliant RJ-45 connector that can be plugged into the console port of
the switch. At the other end are DB-9 (male) connector and DB-25 (male)
connector. You can plug either of them into the DB-9 (female) or DB-25 (female)
port of the modem as needed. The following figure illustrates the AUX cable.

Connecting category-5 shielded cable
Step 1: Plug one end of the network cable into the desired Ethernet RJ-45
connector on the switch.
Step 2: Plug the other end of the cable into the RJ-45 port of the peer device.
Connecting Fiber
n
All the megabit and gigabit optical modules available for the Switch 8800 Family
are SFP modules that provide LC user ports.
Introduction to fiber connector
n
■
When selecting a fiber network facility, make sure that the type of the
connector and the fiber match the adopted optical port.
■
Before connecting the fiber, make sure that the receive-end optical power does
not exceed the upper threshold of the receiving optical power. Excessive
receiving optical power is very likely to burn the optical module.
Fiber connectors are indispensable passive components in an optical fiber
communication system. Their application allows the removable connection
between optical channels, which makes the optical system debugging and
maintenance more convenient and the transit dispatching of the system more
flexible. Among various fiber connectors, only LC connector will be introduced
here.

CHAPTER 4: SWITCH INSTALLATION
Figure 51 LC connector
Connecting fiber
Step 1: Plug one end of the fiber into the SFP optical module of the Switch 8800
Family.
Step 2: Connect the other end of the fiber into the corresponding device.
c
CAUTION: When the optical interface has not been connected with a fiber
connector or its dust-proof mesh is open, there might be some invisible radiation
emitted from the optical interface. So do not look into the optical interface
directly.
Cover the optical interface if there is no connector plugged in.
Cable Routing
Recommendations
Freestanding Switch on
Tabletop
Cabinet-Mounting
Switch
For only selling an integrated chassis, you do not have to care about the cabling
inside or outside the cabinet. All the I/O module cables are routed from the left
side of the chassis (along the cabling channel), and the chassis power cords
(AC/DC power cords) are routed in the front of the chassis.
If the switch is mounted in a 19-inch standard cabinet or B68-22 cabinet, the I/O
module cables are bound on the cabling rack at the left side of the chassis and are
routed up or down to pass through the chassis top or the raised floor depending
on the available equipment room condition (that is, the signal cables are routed
into the chassis either from the cabling rack on the chassis top or from the cabling
trough under the floor) of the exchange office. The power cords run along the
left-front of the chassis and out of the chassis either from the top or the raised
floor depending on the equipment room conditions (DC power distribution
cabinet, lightning protection box, and terminal block, etc.) of the exchange office.
Cable Management
Cable Management
Requirements
■
Bundle and put the cables inside the cabinet in a straight and neat way. No
intertwinement or bending is allowed.
Cable Management
71
Figure 52 Cable bundling example I
Intertwined
Bent
■
The bending radius of cable body cannot be less than twice of the cable
diameter. The bending radius of the cable cannot be less than 5 times of its
diameter at the place where it is led out of the connector;
■
Different cables (power cord, signal cable, PGND wire, etc.) should be cabled
and bundled separately rather than together in the cabinet. If they are close to
each other, you can cable them in cross-shape. For parallel cabling, the space
between power cord and signal cable should be no less than 30 mm (1.2 in);
■
The cable binding rack and cabling channel inside and outside the cabinet
should be smooth and without sharp edges or tips;
■
The metal cable management hole should have a smooth and fully rounded
surface or wear a insulating bush;
■
Use the right type of ties to bundle the cables. Do not bundle cables with
joined ties. 3Com Corporation provides the following types of ties: 100 x 2.5
mm (3.9 in x 0.1 in), 150 x 3.6 mm (5.9 x 0.1 in), 300 x 3.6 mm (11.8 x 0.1 in),
530 x 9 mm (20.9 x 0.4 in), and 580 x 13 mm (22.8 x 0.5 in);
■
Cut the extra parts of the ties neatly after bundling the cables, leaving no sharp
or angular tips. See the following figure:
Figure 53 Cable bundling example II
72
CHAPTER 4: SWITCH INSTALLATION
■
Bundle the cables wherever cable bending cannot be avoided. However, the
cable ties cannot be placed inside the bending area in case of the likelihood of
cable core break due to excessive stress. See the following figure.
Figure 54 Cable bundling example III
■
The spare cables or excessive cable parts should be folded and bundled and
placed at a right place in the cabinet or on the cabling channel. A “right place”
refers to the place where the cables will not affect the operation of the device
or impair the device, or be damaged;
■
The power cords cannot be tied on the guides of any mobile components;
■
Reserve some redundancy for the cables connecting to the mobile parts, the
PGND wire of the door for example, to free the cables from possible stress.
Such a mobile part should be installed in such a way that the extra cable
segments will be kept from contacting the heat source, sharp points or edges.
Use high temperature cables near the heat sources;
■
For the cable terminals fixed using screw threads, the screws or nuts should be
securely fastened and prevented from loosing. See the following figure;
Figure 55 Cable fixing example

Verifying the Installation
73
■
When using a hard power cord, fix it near its terminal so as to free the terminal
and the cable from stress;
■
Do not use tapping screws to fasten the connecting terminals;
■
The power cords of the same type and in the same direction should be bundled
together and kept neatly and straight;
The following table lists the requirements in the bundling with cable ties.

■
No cable or bundle can tie a knot;
■
The metal parts of the crimped cold-pressed terminal blocks (such as air switch)
cannot stretch beyond the blocks.
Verifying the
Installation
c
CAUTION: Confirm that you have turned off the power before checking,
otherwise, improper connection will hurt people or impair the components of the
switch.
After installing the switch, verify the installation by the following list, ensuring all
the checking results are normal.

SWITCH MONITORING AND
MAINTENANCE
Monitoring the Switch
Although the Switch 8800 Family has undergone a comprehensive factory test
before delivery, an improper installation may cause problems. This chapter
describes how to troubleshoot the Switch 8800 Family.
Troubleshooting Console
Terminal
If the system running properly, when you power on the switch, you will see the
boot information on the console terminal. If the switch is configured incorrectly,
the console terminal may display illegible output or nothing at all.
If the console does not display anything after you power on the switch, check that
the:
■
Power system is working normally.
■
Fabric is working normally.
■
Console cable is connected to the console port on the fabric.
If you find no issues with these items, the problem is most likely one of the
following:
■
The console cable is not connected to the right serial port. That is, the port in
use is not the one configured on the terminal.
■
There are console terminal parameter errors. (According to the parameter
setting requirements, you should set the baud rate to 9600, data bits to 8,
parity to None, stop bits to 1, flow control to None, and select VT100 as your
terminal emulation protocol.)
■
The console cable is not in good condition.
If the terminal displays illegible characters, it is most likely a console terminal
setting error. Check that you have set the baud rate to 9600, data bits to 8, parity
to None, stop bits to 1, flow control to None, and select VT100 as your terminal
emulation protocol.
Troubleshooting the PSU
Table 75 LEDs on the PSU

OUTPUT
It stays ON if the power output is normal, otherwise it is OFF.
FAIL
It stays ON if the PSU has failed, otherwise it is OFF.
80
CHAPTER 6: SWITCH MONITORING AND MAINTENANCE
The following PSU faults may appear on the switch. Follow the instructions
provided to resolve the problem.
Display Power Command Indicates the PSU is Not in Position
The Input LED (green) and Output LED (green) stay ON, but the display power
command shows that the PSU is not in position (but the other PSU operates
normally). This problem is likely caused by a poor connection (badly seated)
between the PSU and the backplane. To correct this:
1 Switch off the power supply
2 Loosen the screws on the PSU
3 Push the PSU into the chassis a little bit
4 Tighten the screws
5 Switch on the power supply to check that the normal state is resumed
The Input LED (green) and Output LED (green) are OFF
Check that the power cords are connected correctly, the power cords are in good
condition, and the power switch has been put in the ON position.
The Fail LED (red) is ON
Check that the:
■
Correct power voltage is in use (90 to 264VAC, 50-60 Hz for AC PSU).
■
Air filter protecting the fan tray is clean. Excessive dust accumulated on the air
filter may block the fan tray from free ventilation and can lead to power supply
failure.
w
If the problem persists, contact 3Com technical support engineers. Do not
disassemble the PSU yourself.
Troubleshooting Fan
Tray
The Switch 8800 Family provides two LEDs on the fan tray as described in
Table 76.

Upgrading software
through console port
(XModem)
XModem is a file transfer protocol used for its simplicity and performance. It
transmits files through serial interfaces, supporting 128 bytes and 1Kbytes in data
units, checksum and CRC checking modes, and multiple transmissions attempts
(usually 10 attempts) when packet errors are found.
XModem completes the transmission by the receiving program (receiver) and the
sending program (sender). In XModem, the transmission begins by sending
negotiation characters from the receiver for the purpose of check mode
negotiation. After passing the negotiation, the sender is allowed to send the first
data packet. Upon receiving the complete packet, the receiver checks the packet
using the agreed upon check mode and sends an ACK if the packet has passed
the check and a NAK if it did not. After receiving the ACK, the sender sends the
next packet; if it receives a NAK, the sender retransmits the previously sent packet.
To run the Xmodem application:

Using TFTP
Trivial File Transfer Protocol (TFTP) transmissions are initiated by the client. When
downloading a file, the client sends a read request packet to the TFTP server,
receives the data packets from the server, and sends the ACK to the server. When
uploading a file, the client sends a write request packet to the TFTP server, then
sends the data packets to the server, and receives the ACK from the server. The
TFTP transmission files have two forms; binary for program transmission and ASCII
for text transmission.
To upgrade the software using TFTP perform the following steps.
n
This procedure uses a Switch 8814 work as the TFTP client.
1 Connect the switch to a PC where the file is located using the
management/upgrade Ethernet port. (You need the IP address of the PC. At the
same time, connect the switch to an external PC (that can be the same one that
contains the file) using the console port.
2 Run the TFTP server program on the PC connected to the management/upgrade
Ethernet port and specify the path for upgrading the application files.
3 Run the terminal emulation program on the PC connected to the console port,
and boot the switch to access the Boot menu.

CAUTION:
■
You must reboot the switch using the reboot command to validate the host
program. If Flash memory space is not enough, you can delete some of the
program files in Flash after completing the Boot ROM loading. (3Com
recommends that you delete the host program that is no longer in use.) Then
upload the host program to the switch using FTP.
■
Make sure that you have saved other the configuration before rebooting.
■
Do not power the switch off during the loading process.
The Boot ROM and host program loading process is now complete.
Using TFTP
Using the CLI to upgrade using TFTP is similar to using FTP. The only difference is
that you use the tftp get command to download software to the switch. In this
case, the switch can only be used as a TFTP client to download the software to its
Flash memory from the TFTP server. Once the download is complete all remaining
steps are the same.
Upgrading the
Application Module
Program
If you have the 360G Fabric (3C17508), download the application software image
files to the compact flash (CF) and then boot from the CF.
If you have the 720G Fabric (3C17539), download the application software image
files directly to the Fabric’s onboard flash.
Troubleshooting the
Software Upgrade
This section describes the problems may occur during the software upgrade.
No response from the fabric serial interface
Make sure the serial interface cable is in good condition and that its attributes are
set correctly.
Uploading the configuration file or host program using FTP fails
Check that the:
■
Configuration is correct and that the FTP server is started.
■
Flash has enough space for the target files.
■
TFTP flag is selected (TFTP is not supported).
The configuration did not save during the I/O module reboot
Before saving the configuration, you must check the operating status of the I/O
module. Do not save the configuration during the I/O module reboot. Otherwise,
the configuration you want to save may be lost.
I/O module program loading fails or you cannot register for a long period
■
Check that the I/O module type is supported on the current host program.
■
Check that the I/O module Boot ROM program matches the host program.
■
Check that the I/O modules are well seated.
■
Insert an I/O module to other slots to make sure it is not defective.
Password Loss
■
95
Check that the host program exists and that the current host program is
running.
Insufficient Flash memory
Password Loss
■
Empty the recycle bin when the I/O module starts.
■
Delete the unused files in the Flash.
If the switch’s Super password or Boot ROM password, contact your local support
representative.

LIGHTNING PROTECTION OF THE
SWITCH
A
Installing a Lightning
Arrester for the AC
Power
c
This appendix describes how to install the lightning arrester for the AC power (a
socket strip with lightning protection)
CAUTION: A lightning arrester is not shipped with the switch. You must purchase
it separately, if needed.
Make sure, when connecting an outdoor AC power cord directly to the switch,
that you connect a lightning arrester to the AC power (a socket strip with
lightning protection) before you plug the AC power cord into the switch. This
helps to prevent damage in the event of a lightning strike. Install your lightening
arrester according to its manufacturer’s instructions.
Figure 64 A Lightning Arrester
Grounding and polarity indicator (red) :
On means that the lines are incorrectly connected
(either the ground wire is not well connected, or the live and zero lines are incorrectly connected).
Check the power supply circuit.

CAUTION:
■
Make sure that the arrester is well grounded before using the lightning arrester
for power.
■
After inserting the switch’s AC power cord plug into the lightening arrester’s
socket, if the green LED is on and the red LED does not alarm, it means that the
lightning arrester’s power is running and the lightning protection function is
active.
■
Make sure that the red LED is on. If there is a problem, determine if the
arrester’s ground wire is well grounded and the live and zero wires are
98
CHAPTER A: LIGHTNING PROTECTION OF THE SWITCH
connected in right direction. When the red LED is on, use a multimeter to
examine the polarity at the arrester’s power socket. If it is same as that of the
power socket in the equipment room, it means that the arrester is not well
grounded. If it is adverse to that of the power socket in the equipment room, it
means that the arrester’s power socket is set to the reverse polarity. In this case,
you should open the arrester’s power socket and correct the polarity. After
that, if the red LED still alarms, it means that the arrester is still not well
grounded.
Installing a Lightning
Arrester for the
Network Port
n
A network port lightning arrester is specifically designed for an 10/100M electrical
interface (an RJ-45 connector in this case) Ethernet port.
Make sure, when connecting an outdoor AC power cord directly to the switch,
that you connect a lightning arrester to the AC power (a socket strip with
lightning protection) before you plug the AC power cord into the switch. This
helps to prevent damage in the event of a lightning strike. Install your lightening
arrester according to its manufacturer’s instructions.
Required tools
■
Phillips screwdriver or flat-module screwdriver
■
Multimeter
■
Tilted wire cutter
Installation procedure
1 Remove the protection paper from one side of the double-faced adhesive tape,
and stick the tape to the surface of the arrester. Remove the protection paper from
the other side, and stick the arrester onto the switch’s chassis as close to the
grounding screw as possible.
2 Cut the arrester’s ground wire to the length of the distance between the arrester
and the switch’s grounding screw so that you can securely tighten the ground wire
to the switch’s grounding screw.
3 Use the multimeter determine if the arrester’s ground wire connects properly
chassis’s grounding screw.
4 According to the instructions provided with your network port arrester, connect
the arrester to switch using the cables (Make sure to insert the outdoor network
cable into the arrester‘s IN end, and the cable that is connected to the switch into
the arrester’s OUT end). Check that the arrester’s indicators display correctly.
5 Use the nylon ties to bundle the cables neatly.

Installation precautions
To ensure that the network port’s lightning arrester does not affect performance,
make sure that the lightning arrester for network port is:
■
Connected properly (see Step 4 in the previous section).
■
Well grounded. The ground wire for the arrester should be as short as possible.
Ensure that it is has proper contact with the switch’s grounding screw using the
multimeter.
■
Installed completely. If the switch has more than one network ports to
interconnect with other devices using outdoor cables, you should install
lightning arresters for all network ports for protection.
